WILKES E. TROUTMAN, OF PITTSBURG, PENNSYLVANIA.

ROTARY ENGINE.

SPECIFIGATION forming part of Letters Patent No. 715,904, dated December 16, 1902.

Application led March 25, 1902. Serial No. 99,890. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, WILKES E. TROUTMAN, a citizen of the United States ot'America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rotary engines, and has for its object the provision of a rotary engine that will dispense with valves, turbinewheel, and the like.

Another object of the'present invention is to provide a rotary engine that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efcient in its operation.

Another object of the present'invention is to provide novel means whereby the engine may be easily reversed when desired; furthermore, to provide a packing and' arrange the movable part-s in such a manner that they will be steam-tight.

My present invention still further aims to provide an engine wherein any motive power-such as steam, air, water, or any other motive powermay be employed.

With the above and other objects in view the invention consists in the novel combination and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specification, and wherein likenumerals of reference indicate like parts throughout the several views,in which- Figure lis a vertical sectional view of my improved rotary motor. Fig. 2 is a transverse vertical sectional View thereof. Fig. 3 is a vertical sectional view of the drivingshaft, showing the bracket connected thereto for the purpose to be hereinafter fully explained.

In the drawings, the reference-numeral 1 represents a suitable base carrying the cylindrical casing 2, and in said base 1 are formed inlet-ports 3 3 and outlet-ports 4 4. These inlet and outlet ports communicate with the inlet-port 5 and the outlet-port 6, between which the partition 7 is formed. These inlet and outlet ports 5 and 6 extend into the openings 8 and 9, formed in the casing 2. Recesses 10 10 are also formed in the casing 2 for the reception of packing-disks 1l 11, which are secured therein in any suitable manner. The interior cylinder 12 is eccentrically mounted in the cylindrical casing 2, said cylinder 12 being secured upon the shaft 14. Upon said shaft 14 are sleeved crank-arms 15, which are pivotally connected at 16 to links 17 and 18, the latter being pivoted at their ends 19 to sliding partitions 20, which partitions extend through openings 21,formed in the cylinder 12, and carry rigid arms 25 on their inner edges. The said shaft 14 extends through the cylindrical casing 2, through the stuffing-'boxes 22. This driving-shaft carries a fly-wheel 23. When it is desired, I may provide a bracket 24, which is secured by means of bolts 25 to the cylindrical casing 2, as shown in Fig. 3 of the drawings. This bracket 24 is adapted to carry the end of the driving-shaft and provide a more efficient bearing for the same. The said bracket may be adjusted incase the bearing in course of .time becomes worn.

The operation of my improved device is as follows: Steam or other motive power being admitted into the inlet-ports 3, 3, 5, and 8 will bear against the face of the movable partition and carry the same around to the outlet-port 9, where the .exhaust will take place through the ports 6 and 4. As the cylinder revolves a reciprocating motion will beimparted to the partitions and rigid arms which will cause the crank-arms to revolve by reason of the link connections 17 and 18, thereby transmitting motion to pulley 23.

The many advantages obtained by the use of my improved device will be readily apparent from the foregoing description taken in conn ection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

IOO

1. In a rotary engine, the combination of a cylinder-casing, having inlet and outlet' ports formed therein, a revolving inner cylinder, diametrically-movable partitions devoid of lateral movement, a shaft journaled in said cylinder-casing, arms sleeved on said shaft, link connections between said partitions and arms, substantially as described.

2. In a rotary engine, the combination with an outer casing, a hollow inner cylinder eccentrically arranged therein, a shaft journaled therein, crank-arms carried by said shaft, partitions having a movement in direct aliuement with the aXis of said cylinder mounted therein, rigid arms secured on the inner edges of said partitions, and links pivotally connected to said rigid arms and the said crank-arms, substantially as described. In a rotary engine, the combination with an outer cylindrical casing having inlet and outlet ports formed therein, an inner rotatable cylinder eccentrically mounted in said casing, a shaft journaled in the said casing, arms sleeved upon said shaft, rods connected to said arms, and movable partitions operated by said rods, substantially as described.

In testimony whereof I aiix my signature in the presence of two witnesses.
